Inefficient Regular Expression Complexity

CVE-2024-52798

High
7.7/10

Summary

path-to-regexp turns path strings into a regular expressions. In certain cases, path-to-regexp will output a regular expression that can be exploited to cause poor performance. The regular expression that is vulnerable to backtracking can be generated. This issue affects path-to-regexp package versions through 0.1.11. Users are advised to upgrade to 0.1.12. This vulnerability exists because of an incomplete fix for CVE-2024-45296.
